Thank you for contacting 3M Marine and Specialty Vehicle Department.
If the adhesive sealant is:
UNCURED
Clean surfaces with 3M General Purpose Adhesive Cleaner (part number
#08984) or acetone. DO NOT use alcohol-containing solvents, which will
inhibit the cure of the sealant.
CURED
Polyurethane adhesive sealant must be removed mechanically if cured.
Use a
knife, razor blade, piano wire, putty knife or sandpaper.
Heating to remove 5200 and 4200 is not recommended because of the vapors
given off and possible damage to the substrate.
5200 is meant for permanent applications. If removability is important in
your application and you still need adhesive qualities use 3M Marine
Adhesive Sealant Fast Cure 4200. 3M™ Marine Adhesive/Sealant 4200
performs the same as 5200 with half the strength of 5200, therefore,
easier
to remove.
3M does not make any product for use in bedding boat windows. 3M 5200,
5200
Fast Cure and 4200 Fast Cure are not recommended as an
adhesive/sealant for
the installation of glass, polycarbonate or acrylic windows. Inconsistent
adhesion to these unprimed substrates, specific design of the window and
movement due to thermal expansion and flexing may cause application
failure.

I had fairly good results with a heatgun, although indeed it smells
bad and changes into a sticky goo.
